Consumer review (newegg.com)

Great amp for the price

 

I have it hooked up to a Punch XLC 4 ohm amp, and it hits very hard. Outside of the car you can hear the trunk vibrating; and at that point the lights will start flickering as well. Be sure to disable any bass boost enabled on the head unit before...

Small amp, but has a lot of power in that little amount of space. Hits very hard, without any noticeable distortion. The LED light adds a nice touch to its aesthetic as well. Installation was easy, and it comes with the necessary allen wrenches to wire...

After using this for almost a week I can't think of anything bad about it.

Good Amp

 

works well with Pioneer 12" Champion Series also found on newegg. I have this hooked up running 2 ohm and it hits very hard.

Great for single sub setups

none so far

Super sweet

 

Other retailers get 200+ for this amp. Also, ordered this on sunday night it showed up tuesday morning. Newegg shipping is unbeatable.

Cool clean power. I am running this at 2ohms and haven't had a single issue. no clipping or fading, great amp. This for the money is Awesome!!!

This amp does exactly what it should. But it is missing a few things. No rca output, no dedicated spk level input(not a big deal), the bass boost only has three settings, other than that no cons.

Pioneer=Best Quality for low price

 

Excellent sound and good settings. It does not consume huge amounts of power, since mine is connected to my computer's power supply through a 20gage wire and works fine (until the amp wiring comes, and it will be installed in the car)

Does not include the wiring

Product Specifications

The superior efficiency of a Class-D amplifier means higher power output and greater compactness than an analog amplifier offers. Class-D amplifiers overcome the inefficiencies of traditional Class-A or AB amplifiers. Pioneer's Class-D amps transform very little power into heat so a higher percentage of the power supply (67 %) is transformed into the load. This results in a very compact amp which needs less input power to produce very high output power. The Class-D amplifier's PWM (Pulse Width Modulator) modulates the original audio input signal with a triangulated signal wave which has a much higher fixed frequency. The result is a digital signal which contains both the input signal and a band of frequency components around the modulation frequency. A LPF (Low Pass Filter) then filters out the high frequency pulses and the resulting amplified output signal is then sent to the subwoofer and/or speakers. Bass boost gives you more control over how your music sounds. It lets you set the optimal bass level for each speaker/sub connected to the GM-D7400M, so the tone controls from your headunit can do what they do best. And because this is selectable bass boost, you can set the level at 0dB, 6dB, or 12dB, whichever sounds best to you. Built into the GM-D7400M is a very smart crossover network. It works like a gateway, routing the big bass signals (adjustable from 40 to 240Hz or lower, at -12dB/octave) and filtering out higher-frequency signals to that subwoofer. This optimizes your system's efficiency and delivers the best possible sound quality. The GM-D7400M's speaker level inputs allow you to connect your OEM unit (or any unit that doesn't have the typical RCA-type inputs) without having to buy add-on adapters. So, the install goes faster, you save money, and you've got a Pioneer amp in your vehicle.
